Reorganization of oral anticoagulant (warfarin) treatment follow-up

To evaluate the impact of the reorganization of oral AC treatment management in a primary healthcare setting in terms of quality of care and cost of care. The evaluated reorganization involved the adoption of an AC nurse service model supported by the use of information and communication technology for storing and handling follow-up data.

Statistical analysis of AC follow-up data, personnel task distribution and resource use analysis, and survey of personnel experiences.

The Paloheinä health station in Helsinki, Finland.

All 122 Paloheinä patients on oral AC treatment and the related Paloheinä personnel. Also, follow-ups from two comparison health stations from Helsinki were used.

Laboratory P-INR and follow-up density distributions before and after follow-up reorganization for Paloheinä and comparison station patients, task distribution, and personnel resource use in treatment guideline assignment before and after reorganization and gathered personnel experiences.

No statistically significant changes (Pearson's chi-square test, p < 0.05) were observed in P-INR distributions, considering also the comparison stations. Adoption of the AC nurse model resulted in a 66%/34% task distribution between nurses and physicians in guideline assignment. Personnel resource use analysis showed a cost decrease of 1.61 euros per follow-up in guideline assignment. Users who responded to the survey were generally satisfied with the reorganization and its subjective impacts.

Reorganization resulted in a potential reduction in cost of care per follow-up without a change in the observed quality of care in the Paloheinä setting. Personnel generally accepted the reorganization.
